What changed

The USPTO granted Citibank, N.A. Patent US12591501B1 titled 'Testing functionality of and generating on-chain programs' on March 31, 2026. The patent covers two systems: one for generating on-chain programs by receiving generation requests, determining required models, retrieving associated functions, determining blockchain operations, setting parameters, and generating program code; and another for testing on-chain programs by installing them on a test blockchain, generating testing operations, inputting them into cryptography-based storage applications, and generating notifications when failed results exceed a threshold. The patent includes 18 claims classified under G06F 11/3608 and H04L 9/50.

Patent grants do not impose compliance obligations on regulated entities. However, banks and technology companies developing blockchain applications should review the patent landscape to understand existing intellectual property in on-chain program testing and generation. Companies may want to conduct freedom-to-operate analyses before implementing similar systems to avoid potential infringement issues.

Abstract

Systems and methods for generating and testing on-chain programs are disclosed herein. A system for generating on-chain programs may receive a request to generate on-chain program code for an on-chain program and determine a model required for the program. The system may retrieve functions associated with the model and determine blockchain operations to be added to the program. The system may determine parameters for blockchain operations and generate on-chain program code. A system for testing on-chain programs may install an on-chain program onto a test blockchain and retrieve functions associated with a model generated for testing. The system may generate blockchain operations for testing and input each operation into a cryptography-based storage application. The system may cause execution of the operations and receive results. Based on determining that a number of failed results exceed a threshold, the system may generate a notification.
